Where is the Regal thermostat?

Installed on the intake pipe of the engine. Located on the exhaust pipe side below the throttle of Regal thermostat. Damage to the thermostat will cause the engine heat to be unable to dissipate effectively, the engine water temperature will rise, and the water temperature alarm light will be on. Results The engine water temperature was too low, the water temperature rose slowly, the fuel consumption increased, and the engine was abnormal. The judgment method of thermostat is as follows: 1. After the engine is started, open the filler cap of the cooling water tank to see if there is water flow in the cooling water tank. If not, it means that the thermostat is damaged or something is stuck between the main valve switches; You can judge by feeling the temperature of the upper and lower pipes with your hands. Start the engine first, and touch the upper and lower water pipes after 3 minutes. If it is a good thermostat, the temperature of the upper tube and the lower tube is different. Generally, the upper water pipe is hot and the lower water pipe is cold. When the engine water temperature reaches 90℃, the upper and lower water pipes are heated, which proves that the thermostat is good. If the temperature of the upper and lower pipes is the same after the engine is started, the thermostat is broken; 3. Dismantle the thermostat from the car to do hot water and cold water experiments, and observe whether the thermostat will open with the increase of water temperature, and whether there is hairpin phenomenon.
